Description

Use the ejector plate to move the slider

technical field

The utility model relates to an injection mold, in particular to a sliding block which utilizes a thimble plate to act.

Background technique

Plastic injection molds are tools for producing plastic products and are widely used. For two-color molds or some molds with special requirements, the mold often cannot use the oblique pin to drag the slider to move according to the normal structure due to space or product structure itself. To solve this problem, the slider is often changed to an oil cylinder or Three-plate mold form, which not only needs to enlarge and thicken the template to increase the cost, but also has complex and unstable mold structure, resulting in low product qualification rate and other problems.

Contents of the invention

The purpose of the utility model is to provide a stable and reliable action and a compact overall structure using a thimble plate action slider.

For achieving the above object, the technical solution of the utility model is:

The utility model is an action slider utilizing a thimble plate, including a fixed template, a movable template, a locking block, a slider, a slider thimble, a thimble plate, and a thimble; the fixed template is set opposite to the movable template, and locked The upper end of the block is fixed on the front mold core on the side of the fixed template; the slider has a chute, the inner groove wall of the chute is an inclined plane, the outer wall of the slider is an inclined plane, the slider is slid on the movable template and the slider The inclined surface of the outer wall of the outer wall is against the inclined surface of the lower part of the locking block, the inclined surface of the chute of the slider is pressed against the inclined surface of the upper part of the slider thimble extending into the chute, and the lower end of the slider thimble is fixed on the thimble plate; The lower end is fixed on the thimble plate, and the upper end of the thimble extends into the cavity.

There are two slide blocks, and the two slide blocks are arranged opposite to each other and are respectively located on both sides of the locking block, and can respectively lean against the slopes on both sides of the lower part of the locking block.

After the above scheme is adopted, since the utility model includes a locking block, a slider, a slider thimble, a thimble plate, and a thimble, the slider is provided with a chute that abuts against the slider thimble, and the slider is driven by the slider thimble. It can be separated from the undercut of the product, and the outer inclined surface of the slider can be firmly locked against the locking block. Therefore, the utility model has the advantages of simple parts, easy manufacture, stable and reliable movement, and compact overall structure. Wait for the problem to increase and thicken the mold.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

detailed description

As shown in Fig. 1 and Fig. 2, the utility model is a sliding block that utilizes a thimble plate, including a fixed template 1, a movable template 2, a locking block 3, a slider 4, a slider thimble 5, a thimble plate 6, and a thimble 7.

The fixed template 1 is arranged opposite to the movable template 2, and the upper end of the locking block 3 is fixed on the front mold core of the fixed template 1; the slider 4 has a chute 41, and the inner groove wall 411 of the chute 41 The outer wall 42 of the slider 4 is a slope, the slider 4 is slid on the movable template 2 and the slope of the outer wall 42 of the slider 4 is against the slope 31 of the lower part of the locking block 3, and the slope of the chute 41 of the slider 4 411 abuts against the slope 51 on the upper part of the slider thimble 5 extending into the chute 41, the lower end of the slider thimble 5 is fixed on the thimble plate 6; the lower end of the thimble 7 is fixed on the thimble plate 6, and the upper end of the thimble 7 into the cavity.

In this embodiment, there are two sliders 4 , and correspondingly, there are two sets of slider thimbles 5 and thimbles 7 . The two sliding blocks 4 are arranged opposite to each other and are respectively located on both sides of the locking block 3 , and can respectively lean against the slopes 31 on both sides of the lower part of the locking block 3 .

Action principle of the utility model:

As shown in Figure 4 and Figure 5, the front and rear molds are opened like normal molds. When they are opened to a certain distance and stop moving, the ejector pin 10 on the injection molding machine pushes the ejector plate 6 forward, because the ejector pin 7 is installed on the ejector plate 6 The thimble 7 will also move relatively together. When the slope 51 on the top of the slider 5 hits the slope of the inner groove wall 411 at the bottom of the slider 4, the slider 4 starts to move backward until the slope 51 on the top of the thimble 5 and the slider 4. The slope at the bottom is separated, and the slider 4 starts to stop moving. At this time, the thimble 7 under the product 20 just pushes against the product 20. When the thimble plate 6 continues to move forward, the product 20 is separated from the mold core until the surface of the thimble 7 is attached to the movable template. 2. At the bottom, the ejector plate 6 stops moving, and the product 20 has completely fallen off at this time. Finally, the ejector pin 10 on the injection molding machine retreats, pulling the ejector plate 6 to move backward until the gasket behind the ejector plate 6 touches the bottom plate 8, and the ejector pin 7 Stop retreating, and the mold opening action ends so far.

Manufacture method of the present utility model:

First, make a locking block 3 according to the normal structure. The locking block 3 is positioned by a boss and fixed with screws on the front mold. A chute 41 is made in the middle of the slider 4. A slope 411 is added near the bottom. Out of the slider thimble 5 of the inclined plane 51. As shown in FIG. 3 , the cup head 52 of the thimble 5 of the slider cuts a straight face 53 and is installed on the thimble plate 6 to prevent the thimble from rotating.

The above is only a preferred embodiment of the utility model, so the scope of implementation of the utility model cannot be limited with this, that is, the equivalent changes and modifications made according to the patent scope of the utility model and the content of the specification should still belong to the utility model. Within the scope covered by the utility model patent.
